SAWING APPARATUS.

SPECIFICATIONforming part of Letters Patent I; 0. 765,771, dated July26, 1904.

Application filed August 1, 1903.

T (ZZZ It'll/0m, it may concern.-

Be it known that I, EDWIN E. FRANK, a citizen of the United States,residing at Hastings, in the county of Dakota and State of Minnesota,have invented certain new and useful Improvements in Sawing Apparatus,of which the following is a specification.

My invention relates to improvements in sawing apparatus, its objectbeing to provide a simple and effective power-driven sawing apparatuswhich may be used for sawing standing or fallen timber.

To this end my invention consists in the features of construction andcombination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of my improved sawing apparatus arranged forsawing standing timber. Fig. 2 is a top view of the same. Fig. 3 is asection on line y y of Fig. 2. Fig. 4 is a side elevation of the frontof the machine arranged for sawing horizontal timber. Fig. 5 is an endview of Fig. 1. Fig. 6 is an end view of Fig. 1, and Fig. 7 is a detailof guiding means for the saw.

As shown in the drawings, the supportingframework is made up ofhorizontal beams 1 and uprights 2. Slidable between the uprights 2 is aframe 3, which is adapted to be raised 'and lowered by a lever 4,fulcrumed upon the upper cross-bar 5 of the uprights, as shown in Fig.5. Journaled in the frame 3 is a horizontal shaft 6, carrying upon itsouter end a pulley 7, adapted to be connected with a source ofpower,'such as a gasolene-engine, (not shown,) and having mounted uponits inner end a beveled gear 8. The beveled gear 8 intermeshes with asimilar gear 9, carried by the upper end of the shaft 10, said shaft 10having journal-support in the lower cross-bar of the frame 3. Carried bythe lower end of the shaft 10 is a disk 11, eccentrically connected tothe under side of which is a pitman 12. The outer end of the pitman 12is connected by a pin 13 to the adjacent end of a bar let, whichsupports a saw 15, as illustrated in Figs. 1 and 3. The rear end of thebar let is preferably connected by the pin 13 with a block 38, slidablein the guides 16. The guides Serial No. 167,828. (No model.)

are supported by rods 17 from the frame 3. The saw-supporting end of thebar 14: slides through an opening 18 in a block 19, said block beingslidably supported between the cross-bars 20. The ends of the cross-barsare connected by bolts 21 and are supported from the frame 3 by rods 22.The block 19 is connected at its opposite ends by cables 23 and 23 toweights at and 24:, the cables passing intermediately over sheaves 25and 25 and 26 and 26 The weight 24c is heavier than the weight 24, so asto draw the slidable block 19 across the apparatus to guide the sawthrough the timber. The forward end of the saw works through a block 27,said block being supported from the frame 3 by a rod 28.

In using my apparatus for sawing horizontal timbers I remove the saw 15andconnect a frame 29 with the frame 1 by hooks 30. (Jarried by theframe 29 are uprights 31, between which slides a weight 32, formed withan opening 33, through which slides a saw-supporting bar 3 1, which Iconnect with the end of the bar 14 byahinge 35. The block 32 isconnected by the cable 36 with a lever 37, by means of which it israised.

In the use of my apparatus where it is desired to saw upright timbersthe apparatus is fitted up as shown in Figs. 1 and 3, inclusive. Thepower then being applied through the pulley 7 the saw will be actuatedthrough the intermediate gearing and the saw guided through the timberby the weights 24: and 2 t It will be understood that the frame 3 willfirst be set by the lever 1 at the desired height to regulate the heightof cut.

In sawing horizontal timbers the apparatus will be connected as shown inFig. 4 and the saw actuated as above described. The saw will be guidedthrough the horizontal timber by the weight of the slidable block 32.Both where the apparatus is fitted up to saw upright as well ashorizontal timber the frame 3 will be adjusted to the desired height.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A sawing apparatus of the class described, comprising in combinationa vertically-slidable frame, means for supporting said frame in adjustedpositions, a crank-disk carried by said frame, a slidable block, apitman connecting said crank-disk and block, a saw connected with saidblock, a transversely-slidable block supporting the rear end of saidsaw, and a guide supporting the free end of said saw.

2. A sawing apparatus of the class described,

comprising in combination a vertically-slidable frame, means forsupporting said frame in adjusted positions, a crank-disk carried bysaid frame, gearing supported by said frame for connecting saidcrank-disk to a suitable source of power, a block arranged at the rearof said crank-disk and slidable toward and from the same, a pitmanconnecting said crankdisk and block, a saw pivotally supported by saidblock and extending forwardly past saidcrank-disk,atransversely-slidableguide-block supporting said saw infront of said crankdisk, actuating-weights connected with said block, aguide supporting the free end of said saw, and brace-rods connectingsaid guide with said frame. v

In testimony whereof I afliX my signature in presence of two witnesses.
